* In spring, drone spraying generally starts around April, so as to prevent and control crop diseases and insect pests in time and ensure agricultural production.
Summer is a hot and rainy season, and crops are easily affected by pests and diseases. Drone spraying will also be carried out in time to ensure the healthy growth of crops.
Autumn is the harvest season, and drone spraying is also carried out during this period, which can reduce pesticide residues and ensure crop quality.
In practice, please determine the spraying time of UAV according to the local climatic conditions and crop types, as well as the safe use interval and regulations of pesticides.
